Engine Lab man. I was going to have mine done elsewhere but seriously tour both shops and your mind will be made up. You can have your motor built in a dusty, greasy, shop OR Engine Lab can use some of the best equipment around in a spotless A+ facility. THey even go as far as hooking your motor up to a machine after its built and pumping oil through it to make sure everything flows evenly. To me, the extra money is more than well spent when you know for fact that the engine will be done RIGHT THE FIRST TIME! Hell if its good enough for one of the most pickiest and "it has to be done this way" race teams, its more than good enough for me.
